Abstract
본 발명은 개선된 원료 폴리머점도, 카본블랙이 보강된 상태에서 좋은 가공성 및 경화되고 카본블랙이 보강된 상태에서 감소된 히스테리스를 갖는 디엔폴리머 또는 코폴리머를 제공한다. 이 디엔 폴리머 및 코폴리머는 주폴리머 또는 코폴리머 쇄에 탄소-주석 결합을 함유하는 디엔폴리머 또는 코폴리머 쇄와 하기 구조식을 갖는 헤테로 사이클릭 질소기를 함유하는 비닐화 합물로부터 유도된 말단을 함유하는 디엔폴리머 또는 코폴리머 쇄의 혼합물을 함유한다 :The present invention provides diene polymers or copolymers having improved raw polymer viscosity, good processability with carbon black reinforced and reduced hysteresis with carbon black reinforced. These diene polymers and copolymers are diene-containing diene polymers containing carbon-tin bonds in the main polymer or copolymer chains or endene-containing vinylene compounds containing heterocyclic nitrogen groups having the structure Or contains a mixture of copolymer chains:
여기에서, R1과 R2는 H, 알킬, 알킬아릴, 아릴 및 O,N-함유 알킬, 알킬 아릴 및 아릴기로 이루어진 그룹으로 부터 선택되고, X는 하기식으로 이루어진 그룹으로 부터 선택된다.Wherein R 1 and R 2 are selected from the group consisting of H, alkyl, alkylaryl, aryl and O, N-containing alkyl, alkyl aryl and aryl groups, and X is selected from the group consisting of
여기에서, R3, R4, R5, R6, R7및 R8은 H, 알킬, 알킬아릴, 아릴 및 O,N-함유알킬, 알킬아릴 및 아릴기로 이루어진 그룹으로 부터 선택된다.Wherein R 3 , R 4 , R 5 , R 6 , R 7 and R 8 are selected from the group consisting of H, alkyl, alkylaryl, aryl and O, N-containing alkyl, alkylaryl and aryl groups.
디엔 폴리머 또는 코폴리머는 폴리할라이드 주석결합제를 이용하여 음이온 중합에 의해 얻어진 일부의 리빙디엔 폴리머 또는 코폴리머를 먼저 결합시키고 헤테로사이클릭 질소를 함유하는 비닐 화합물을 사용하여 잔여 리빙디엔 폴리머 또는 코폴리머를 말단 결합시키므로서 제조된다. 최종 디엔폴리머 또는 코폴리머는 개선된 원료 폴리머점도를 가지며 카본블랙과 컴파운딩 될때 비경화상태에서 좋은 가공성을 가지며 경화상태에서 감소된 히스테리시스를 갖는다. 그러한 폴리머는 감소된 롤링저항성을 갖는 타이머 트레드용 엘라스토머 조성물을 제조하는데 이용될 수 있다.The diene polymer or copolymer is first bonded to some living diene polymer or copolymer obtained by anionic polymerization using a polyhalide tin binder, and a vinyl compound containing heterocyclic nitrogen is used to remove residual living diene polymer or copolymer. It is prepared by end bonding. The final diene or copolymer has an improved raw polymer viscosity, good processability in the uncured state when compounded with carbon black and reduced hysteresis in the cured state. Such polymers can be used to prepare elastomer compositions for timer treads with reduced rolling resistance.
